The Twilight Experiment

It had been a day since the two Twilights had finished the Twilight Experiment. Once they decided that it was a success, Twilight returned to her world, while her alicorn counterpart had certain matters to attend to before visiting in the morning. Luckily, they had already deemed their little experiment a success. Twilight smiled to herself, remembering the intimate moments the two shared, learning that they did have a connection, and she wanted to have more of that.

As much as she loved her doppelganger, Twilight was a little relieved to be on her own tonigh. As it allowed her to finish business with something that's been plaguing her mind since the beginning of all this and was the very catalyst for this experiment in the first place. The girl laid upon her bed, wrapping the covers over her body and she finally closed her tired eyes, taking a while to fall asleep, ready to make one last visit to that person.

Midnight Sparkle.

When her eyes opened, Twilight once more found herself within the endless pink void, and also Midnight's realm of her own mindscape. It had been a place she's seen times before. When she feared her, and now... she welcomed her presence. As of now, Midnight was no threat and she was forever grateful of Sunset's help in making sure that was truly the case in the first place.

Now, the girl turned her head and noticed her dark counterpart slowly hovering towards her. Twilight didn't do anything and remained frozen, awaiting a reaction from the inner demon.

But before Midnight said anything, she gently wrapped her arms around the girl's neck. "Well well. Look who decided to come back." Midnight pursed her lips as she feigned sadness, "About time, and I was getting rather lonely in here." she teased, giving Twilight a quick kiss. The girl closed her eyes before separating the two of them.

Twilight wrapped Midnight's fingers around her own, stroking her hands around her arms until reaching her palms. "Okay, Midnight. I have to ask... Why help me?" she asked, confused over the action of who she considered to be an enemy.

A devious smirk was seen on the demoness' face, "Oh, wouldn't you like to know, Sparkle?" she poked Twilight's nose playfully before placing her hands on her good counterpart's shoulders. She spun Twilight around, catching the girl off guard as she let out a quiet yelp in surprise, feeling Midnight massage her.

The demoness chuckled darkly whike she massaged Twilight's shoulders, "Jeez, you're tense. Your lucky I gave you that confidence boost. Being stuck in a body this shaky and constantly nervous is a sin in itself." Midnight leaned in to whisper in Twilight's ear, "But then again, can you say you hated what we've done together?" she pecked Twilight's cheek from behind, spinning her good counterpart once again so they were face to face.

Twilight stammered nervously, "That... T-That d-didn't answer my question."

Midnight giggled and groped Twilight's breasts, "Do you want me to, Sparkle? I can tell you enjoy this... Would you want that mystery spoiled already? Heh, very well." she cooed, hearing the girl moan as Midnight's hands rubed her boobs. "Let's just say... I'm getting bored being in your subconscious. Even if I can't take your body, I may as well have some fun."

"F-Fun?" Twilight gasped out.

The demoness moved her hands to cup Twilight's chin, "Ease up, Sparkle. I'm not plotting anything. If I am to be here, I may as well do something. I've been able to enter your dreams and decided you needed a push in admitting those curious feelings of yours for the other Twilight. May as well do something in here." she stuck her tongue out.

"S-So, why are you still doing this?" Twilight asked, blushing. She could feel the aura around Midnight's face and fake horn heating up her face as she got closer.

Midnight planted a deep kiss on Twilight's lips, the girl not objecting and instead choosing to reciprocate her demoness counterpart. Twilight hugged Midnight tightly, feeling her doppelganger's fingers stroke her back downwards, reaching for her rear and lightly pinching it, causing her eyes to snap open for a second at the sudden feeling, but they closed again. Twilight deepened the kiss, running her fingers through Midnight's long, wild hair.

Twilight moved away from the demoness, seeing her smug smile as they separated. Midnight smirked, "Just admit it, Sparkle. You're going to get lonely with your counterpart being on her world most of the time. And you don't want me to stop this."

"But--"

Midnight raised a hand before the girl could make an objection, "I'm in your head, remember? I can sense these emotions. Deep down, despite your initial protests, you want to keep what we have." she embraced Twilight by the waist with one arm while holding her hand with the other, pushing her in closer to her. Their hot breath could be felt on their faces. The two remained like that, with tingles being sent down Twilight's spine, feeling Midnight getting ever closer to her lips. It was almost teasing in a way, but Twilight didn't fight the feeling she was having.

Pulling Midnight forward, Twilight closed the distance between them. She moved her palms all around Midnight's body, feeling her curves, her hips and finally grabbed her breasts. They were larger than her own, which confused her, but Twilight circled her fingers and squeezed them a little. Midnight was surprised by her doppelganger's direct approach, not that she minded of course. It felt good to not have to start things for once.

Twilight and Midnight's tongue danced. To Twilight, this was all real. It was like having Midnight next to her. Her tongue lightly squirmed around the entity's own, feeling Midnight's wet appendage circle around hers. Midnight's fingers managed to squeeze her ass again, causing her to gasp in her doppelganger's mouth.

Midnight tilted her head as she and Twilight hugged one another to push the two of them closer. The feeling of their breasts pressing against one another greatly increased their arousal. They pushed on each other more, never wanting the moment to end.

But they separated once more, but before parting for good, Twilight planted one last peck on her doppelganger's lips. And Midnight flicked her tongue on Twilight's bottom lip. They gazed lovingly at each another in silence, holding the other in a deep embrace. Twilight had her arms wrapped around the back of Midnight's neck while her dark counterpart held the girl by her waist.

At last, Midnight broke the silence, "So, you really want to end this?"

Twilight slowly shook her head and blushed, "N-No... I don't... That was wonderful..."

Midnight chuckled, raising her hands so that she stroked Twilight's cheeks, the girl gently placing her palms upon them. "Very well, Sparkle. A shame it's almost morning. But... maybe we'll do things a little more dirty?" she teased, seductively winking at her doppelganger, who was beginning to fade back to the real world.

Twilight's eyes snapped open, hearing the annoying ring of an alarm. She reached for the snooze button and sat up. Her face was flushed and she wiped some sweat off her forehead. "Oh no... I'm gonna be late!" she said, referring to meeting with her doppelganger over a supposed 'date night'.
